Abstract
A novel light source. A high-frequency power supply (7) is connected with a coil (5) to generate an electromagnetic field oscillating at a high frequency, and the electromagnetic field acts on a thermal radiator (1) (the thermal radiator is a conductor) sealed inside a bulb shell (2). The thermal radiator (1) generates induction turbulence, and an electromagnetic field generated by the turbulence and an electromagnetic field for exciting the turbulence keep opposite to each other. The thermal radiator (1) is suspended in the bulb shell (2), and is continuously heated until the thermal radiator enters an incandescent light-emitting state. In this case, stable thermoluminescence can be achieved by maintaining the balance between the input power of the power supply and the dissipation power of the light source.
Description
本发明属于照明领域，涉及到一种新式电光源。The invention belongs to the field of lighting and relates to a new type of electric light source.
电灯发明以米被大量应用，为人类的生产生活提供了极大的便利，发展至今已经经历了白炽灯、卤钨灯、气体放电灯、LED灯的几代演进，其发展轨迹体现出了对于更高光效、更长寿命、更好光品质的不断追求，本发明旨在提供一种新式的高光效、长寿命、高品质的电光源。The invention of electric lights has been widely used in meters, providing great convenience for human production and life. It has experienced several generations of evolution of incandescent lamps, tungsten halogen lamps, gas discharge lamps, and LED lamps. Its development trajectory reflects the In the constant pursuit of higher light efficiency, longer life, and better light quality, the present invention aims to provide a new type of electric light source with high light efficiency, long life, and high quality.
发明内容Contents of the invention
以高频电源连接线圈产生高频振荡的电磁场，作用在密封于泡壳内部的热辐射体(热辐射体为导体)上。受此作用，热辐射体会产生感应湍流，且湍流所产生的电磁场与激发湍流的电磁场保持反向。因此热辐射体会被磁场力悬浮于泡壳内，脱离与泡壳的接触，且被感应湍流不断加热直至进入白炽发光状态。此时维持电源输入功率与光源耗散功率的平衡即可得到稳定的热发光电光源。A high-frequency power supply is connected to the coil to generate a high-frequency oscillating electromagnetic field, which acts on the heat radiator (the heat radiator is a conductor) sealed inside the bulb. Affected by this, the thermal radiator will generate induced turbulence, and the electromagnetic field generated by the turbulence will remain opposite to the electromagnetic field that stimulates the turbulence. Therefore, the thermal radiator will be suspended in the bulb by the magnetic field force, out of contact with the bulb, and will be continuously heated by the induced turbulence until it enters an incandescent state. At this time, a stable thermoluminescent electric light source can be obtained by maintaining the balance between the power input power and the light source dissipation power.
本发明的优点在于热辐射体与泡壳无直接接触，依靠电磁场悬浮于泡壳内，同时热辐射体不依靠导线及支架结构供电，故无需保持复杂且脆弱的灯丝结构，甚至无需保持固体状态，因此可突破材料自身熔点限制，将热辐射体的热辐射温度极大程度的提高，以达到高效率发光的目的，对于由更高温度造成的更高的蒸发速率依然通过卤钨循环来处理。为达到较好的抑制蒸发的效果，一方面充气成分、总量及压强可做针对性调整，另一方面本光源的工作过程中可以加入有特殊设计的操作步骤，详见后文实施方式。The advantage of the present invention is that the thermal radiator has no direct contact with the bulb and relies on the electromagnetic field to be suspended in the bulb. At the same time, the thermal radiator does not rely on wires and bracket structures for power supply, so there is no need to maintain a complex and fragile filament structure, or even to maintain a solid state. , so it can break through the melting point limit of the material itself and greatly increase the thermal radiation temperature of the thermal radiator to achieve the purpose of high-efficiency luminescence. The higher evaporation rate caused by higher temperatures is still handled through the tungsten halogen cycle. . In order to achieve a better effect of inhibiting evaporation, on the one hand, the aeration composition, total amount and pressure can be adjusted accordingly, on the other hand, specially designed operating steps can be added to the working process of this light source. Please refer to the implementation method below for details.

为了更好地说明本发明的内容以及实用性，以下列举一种具体实施方式，应明确本发明的权利要求及适用范围并不仅限于此处所列举的实施方式。In order to better illustrate the content and practicality of the present invention, a specific embodiment is enumerated below. It should be clear that the claims and scope of application of the present invention are not limited to the embodiments listed here.
本实施方式中以5500K为目标热辐射温度，该温度非常接近太阳光谱热辐射温度且接近钨在常压下的沸点，为比较理想的目标热辐射温度。对于(1)热辐射体的选用，综合性价比来看目前最理想的材料仍然是传统的灯丝材料——钨，本方案中亦采用钨作为热辐射体。In this embodiment, 5500K is used as the target thermal radiation temperature. This temperature is very close to the solar spectrum thermal radiation temperature and close to the boiling point of tungsten under normal pressure, which is a relatively ideal target thermal radiation temperature. Regarding the selection of (1) thermal radiator, the most ideal material in terms of comprehensive cost performance is still the traditional filament material - tungsten. In this solution, tungsten is also used as the thermal radiator.
(2)高压充气内泡壳的制备仍可采用传统卤钨灯的石英玻璃材料，形状、尺寸应做针对性调整以确保卤钨循环顺利进行。充气压力、总量、成分等与传统卤钨灯原理上并无本质区别，针对本案例中更高的温度及钨蒸发速率进行适当调整即可。泡壳可带有红外反射膜以回收红外波段辐射能量，即行业内所谓的IRC技术，现有的成熟技术在传统卤钨光源中节能比例可达约30％(占红外辐射能量的约40％)，其中很大的限制条件在于红外反射光无法聚焦于传统灯丝的精细结构上，而本发明中的热辐射体为一近似球体的实体，非常有利于红外反射光聚焦，且考虑设置二次红外反射层，可预见应能达到更高的红外回收占比(约70％-80％)。(2) The quartz glass material of traditional tungsten halogen lamps can still be used to prepare the high-pressure inflatable inner bulb. The shape and size should be adjusted accordingly to ensure the smooth progress of the tungsten halogen cycle. The charging pressure, total volume, composition, etc. are not fundamentally different from those of traditional tungsten halogen lamps in principle. Appropriate adjustments can be made for the higher temperature and tungsten evaporation rate in this case. The bulb can be equipped with an infrared reflective film to recover infrared band radiation energy, which is the so-called IRC technology in the industry. The existing mature technology can save about 30% of energy in traditional tungsten halogen light sources (accounting for about 40% of infrared radiation energy). ), the big limitation is that the infrared reflected light cannot be focused on the fine structure of the traditional filament, and the thermal radiator in the present invention is an approximately spherical entity, which is very conducive to focusing the infrared reflected light, and it is considered to set up a secondary The infrared reflective layer can be expected to achieve a higher infrared recovery ratio (about 70%-80%).
(3)光学反射罩及透光面罩与传统卤钨灯杯近似，也是成熟技术，在此不做过多表述，特别指出光学反射罩及透光面罩的设置主要出于应用便利方面的考虑，并非本发明中必不可少的部分。(3) The optical reflector and light-transmitting mask are similar to the traditional tungsten halogen lamp cup, which is also a mature technology. I will not elaborate too much here. It is particularly pointed out that the optical reflector and light-transmitting mask are mainly set up for the convenience of application. It is not an essential part of the invention.
(4)外层红外反射泡壳，在传统的卤钨光源中由于可见光辐射总量比例较低导致系统总体回收利用率不高，且单灯功率相对偏低，因此综合考虑到经济效益，现有IRC技术主要针对能量占比较高的近红外部分进行回收，对于辐射能量占比相对较低的中远红外部分的辐射能量基本相当于放弃处理。本发明中可见光辐射占比有显著提升(以5500K为设计目标温度则可见光占比约为44.9％)，单灯功率也不再受到灯丝结构限制，可以依使用需求做到很高，因此对于中远红外波段辐射能量的回收也变得具有一定经济效益，故考虑增设外层红外反射泡壳予以针对性回收，当然也可将此涂层结合在(2)或者(3)中，但会相应增加涂层的设计与制备技术难度。(4) The outer infrared reflective bulb. In traditional tungsten halogen light sources, due to the low proportion of total visible light radiation, the overall recycling rate of the system is not high, and the power of a single lamp is relatively low. Therefore, taking into account the economic benefits, now There is IRC technology that mainly recycles the near-infrared part with a relatively high proportion of energy. The radiation energy of the mid-far infrared part with a relatively low proportion of radiated energy is basically equivalent to giving up processing. The proportion of visible light radiation in the present invention has been significantly improved (with 5500K as the design target temperature, the proportion of visible light is approximately 44.9%). The power of a single lamp is no longer limited by the filament structure and can be very high according to the use requirements. Therefore, for COSCO The recovery of radiation energy in the infrared band has also become economically beneficial, so it is considered to add an outer layer of infrared reflective bulbs for targeted recovery. Of course, this coating can also be combined in (2) or (3), but it will increase accordingly. The technical difficulty of coating design and preparation.
(5)感应线圈通常采用铜质线材或管材绕制而成，在电磁悬浮加热行业中亦有成熟应用，可直接借鉴。(5) Induction coils are usually made of copper wires or pipes, and have mature applications in the electromagnetic suspension heating industry, which can be directly used for reference.
(6)外部导线并无特殊要求，特别指出由于本发明中导线不再与具有较高工作温度的灯座接触，故而对导线护套的耐热要求大幅降低，进而也降低了由此带来的火灾隐患。
(6) There are no special requirements for external wires. It is particularly pointed out that since the wires in the present invention are no longer in contact with the lamp holder with a higher operating temperature, the heat resistance requirements for the wire sheath are greatly reduced, which in turn reduces the resulting fire hazard.
(7)外接电源应该具备可调控的功能，以便配合光源整个工作过程实时调整各项输出参数。(7) The external power supply should have an adjustable function to adjust various output parameters in real time to match the entire working process of the light source.
本发明整体系统工作过程大体分为三阶段：The working process of the overall system of the present invention is roughly divided into three stages:
1、启浮预热阶段。开灯时，电源通电，初始采用低功率输出并调整频率使得(1)电磁悬浮于设计理想光中心位置(可考虑采用适当机械结构辅助校准)，然后逐步提升输出功率将(1)加热至设计目标温度5500K左右。此时(1)处于熔融、悬浮、白炽，状态。系统进入下一阶段正常工作阶段。1. Floating warm-up stage. When turning on the light, power up the power supply, initially use low power output and adjust the frequency to make (1) electromagnetically suspended at the designed ideal light center position (appropriate mechanical structure can be considered to assist calibration), and then gradually increase the output power to heat (1) to the designed The target temperature is around 5500K. At this time (1) is in a molten, suspended, and incandescent state. The system enters the next stage of normal operation.
2、正常工作阶段。此阶段维持电源输出频率与功率使得光源功耗与电源输出保持平衡，则(1)可保持稳定的电磁悬浮及设计目标辐射温度5500K进行设计预期的发光与卤钨循环。在此温度下由热辐射能量——波长相关曲线经与人眼视觉敏感度曲线(明视觉)拟合可计算出可见光波段总体光效约为140lm/W，已经基本与当前LED技术商用高端光源光效水平持平，再结合有效的IRC技术回收利用红外辐射能，有望可达到可见光波段光效200lm/W以上的水平。且辐射光谱真实还原自然光谱。特别指出由于本发明的光源光谱中含有较高比例的短波及紫外成分，为利用荧光粉调节光谱以得到针对使用需求的光谱分布提供了有利条件，加以适当利用可得到更高光效的光谱或满足不同使用需求。2. Normal working stage. At this stage, the power output frequency and power are maintained to balance the light source power consumption and power output. Then (1) stable electromagnetic levitation and the design target radiation temperature of 5500K can be maintained to perform the design expected luminescence and tungsten halogen cycle. At this temperature, it can be calculated from the thermal radiation energy-wavelength correlation curve and the human visual sensitivity curve (photopic vision) that the overall light efficiency in the visible light band is about 140lm/W, which is basically the same as the current commercial high-end light source of LED technology. The level of light efficiency is the same. Combined with the effective IRC technology to recycle infrared radiation energy, it is expected to reach a level of light efficiency of more than 200lm/W in the visible light band. And the radiation spectrum truly restores the natural spectrum. It is particularly pointed out that since the spectrum of the light source of the present invention contains a higher proportion of short-wave and ultraviolet components, it provides favorable conditions for using phosphors to adjust the spectrum to obtain a spectral distribution according to the use requirements. Proper use can obtain a spectrum with higher light efficiency or meet the needs of use. Different usage requirements.
3、保养冷却阶段。关灯时，由于正常工作阶段中(1)温度较高处于熔融状态，故不可立即切断电源，应使电源工作在维持(1)悬浮但逐步降低功率的状态，以让(1)能够逐步冷却至壳体可承受的温度范围。此后方可逐步降低频率(有过往研究表明频率与电磁悬浮力正相关)及功率直至(1)缓慢降落于(2)底部后彻底切断供电。特别指出由于本发明设计工作温度较高，不可避免的(1)材质的蒸发速率会高于传统光源，因此预计有可能存在蒸发速率超出卤钨循环速率的情况，针对这种情况特别设计一个温热保养工作模式。该模式下调整电源的输出参数，使得(2)内表面温度能达到卤钨循环温度的同时(1)也仅处于满足卤钨循环的温度(略高于1400K，远低于正常工作温度)，此温度下蒸发速率极低，卤钨循环速率必然高于蒸发速率，使得正常工作中由于可能存在的卤钨循环速率不足导致的钨在(2)内的沉积得以消除并返还到(1)上。此工作模式可以根据实际使用情况适当设置为每次关灯阶段自动运行一段时间或光源累计工作一定小时数后某次关灯时自动运行一定时间。借此可极大程度保证光源寿命及光通维持率。理想状况下光源自身理论寿命近乎无上限(对于包含IRC技术的光源可能会受到红外反射涂层寿命的限制)，而实际应用中系统整体寿命则取决于外接电源的寿命及稳定程度，故对于相配套的电源也应当予以足够的重视。相关技术另做研究，在此不过多讨论。
3. Maintenance cooling stage. When turning off the lights, since (1) is at a high temperature and is in a molten state during normal operation, the power supply cannot be cut off immediately. The power supply should be kept in a state where (1) is suspended but the power is gradually reduced, so that (1) can gradually cool down. to the temperature range that the shell can withstand. After that, the frequency can be gradually reduced (past studies have shown that frequency is positively related to electromagnetic levitation force) and power until (1) slowly drops to the bottom of (2) and then the power supply is completely cut off. It is particularly pointed out that due to the high design working temperature of the present invention, it is inevitable that (1) the evaporation rate of the material will be higher than that of traditional light sources. Therefore, it is expected that the evaporation rate may exceed the tungsten halogen cycle rate. For this situation, a temperature sensor is specially designed. Thermal maintenance working mode. In this mode, adjust the output parameters of the power supply so that (2) the inner surface temperature can reach the tungsten halogen cycle temperature while (1) it is only at a temperature that satisfies the tungsten halogen cycle (slightly higher than 1400K, far lower than the normal operating temperature). The evaporation rate is extremely low at this temperature, and the tungsten halogen circulation rate must be higher than the evaporation rate, so that the deposition of tungsten in (2) caused by the possible insufficient tungsten halogen circulation rate during normal operation can be eliminated and returned to (1) . This working mode can be appropriately set according to the actual usage to automatically run for a period of time each time the lights are turned off or to automatically run for a certain period of time when the lights are turned off after the light source has been working for a certain number of hours. This can greatly ensure the life of the light source and the luminous flux maintenance rate. Under ideal conditions, the theoretical life of the light source itself is almost unlimited (light sources containing IRC technology may be limited by the life of the infrared reflective coating). However, in actual applications, the overall life of the system depends on the life and stability of the external power supply, so for relative The supporting power supply should also be given sufficient attention. The related technology will be studied separately and will not be discussed in detail here.
以上为本发明的内容，期望在相关领域中能够得到较好的应用与发展。
The above is the content of the present invention, and it is expected that it can be better applied and developed in related fields.
